The Rensair air purifier sucks in the surrounding air from the top inlet perforations. Air travels through the removable pre-filters placed at the top of the machine, which catch and trap larger airborne particles and dust.
A powerful fan pushes the pre-filtered air down into the cylindrical shaped H13 HEPA filter located in the middle of the unit. The fan creates a high static air pressure in the cylinder which is a necessity to allow for sufficient air flow through the high quality H13 HEPA filter and enables a large air cleaning capacity.
As air hits the H13 HEPA filter, bacteria, viruses and smaller airborne particles and pollutants become trapped on it’s inner surface.
An 18w UVC lamp placed in the center of the cylindrical drum continuously illuminates the entire filtration area. This UVC light breaks down the DNA and RNA of pathogens and thereby inactivates them. This continuous disinfection process ensures that the Rensair air purifier is always safe to operate and maintain.
Large volumes of clean air travels out of the unit via the lower perforations. The cylindrical shape of the Rensair Air Purifier allows air to flow out in every direction thereby making it suitable for almost all locations.

HEPA filters are mechanical filters with a capacity for sifting small particles at a much higher rate than any other conventional filter. HEPA stands for high-efficiency particulate air and refers to filters made in accordance with specific requirements. Hospital grade HEPA filters are H13 HEPA and above.
UVC light at 254nm inactivates bacteria and viruses by breaking down the DNA and RNA in them, thereby effectively destroying them. The UVC irradiation dose needed for inactivation varies from pathogen to pathogen. Due to Rensair’s patented design, any bacteria or virus caught on the HEPA filter surface will be exposed to a constant and high irradiation dose meaning the filter is continuously disinfected.
Rensair destroys more than 99.97% of airborne viruses and bacteria. Eurofins Denmark conducted a test to demonstrate the air cleaning efficiency of the Rensair air purifier.
As a control, an aerosol generator added bacteria and viruses into the air before the air flowed into the air purifier. Prior to being treated by the Rensair air purifier, the air was contaminated with >250 pathogens per m3 of air.
After the treatment, the test results show<1 pathogen per m3 of air. Eurofins concluded that the Rensair air purifier removes airborne viruses and bacteria to undetectable levels.
Norconsult tested the Rensair air purifier technology’s ability to remove airborne particles in a room over time.
“The results show that the air purifier, on its own, cleans the air almost equally efficiently at two selected measuring points in the 93m3 test room and is thus little affected by placement.” and “In a ventilated room [i.e. room with an HVAC system running], the air purifier will also be able to get help from the ventilation system to create full circulation and thus removes particles more efficiently.”
Rensair inactivates airborne viruses incl. the coronavirus family.
While the H13 HEPA filter captures airborne pathogens, the germicidal ozone-free UVC light inactivates viruses and bacteria trapped on the filter surface. Oslo University Hospital has clarified the effectiveness of this ability.
“Based on the tests performed by accredited laboratories and scientifically published literature, one can conclude that the Rensair air cleaner effectively reduces the level of microorganisms, such as bacteria, viruses, moulds and yeasts in the air.”

The Rensair air purifier was developed decades ago by Henrik Hendriksen, a Danish engineer and inventor. For five years he represented Norway at the indoor climate association EUROVENT, helping to set the industry standard for truly clean air. His life-long experience with ventilation technology, combined with a desire to help relieve his son’s severe allergies, led to the development of the Rensair air purifier.
Today, Henrik’s twin sons Frederik and Christian Hendriksen continue to manufacture and distribute this technology worldwide.
